>> well, the obama administration has established a policy of a so-called public safety exception to the miranda rule where for some period of time, it's not entirely clear how long, a suspect can be questioned without miranda warnings and that apparently is what's happening here. again, it's complicated somewhat by the fact that we didn't know exactly what tsarnaev's medical condition is and how many questions he can answer. apparently he's answering some questions in writing. so i don't really see lindsey graham's proposal as all that differentwhat's going on now. he seems to suggest a longer process of questioning him, but the obama administration has also committed to some period of questioning. now, this all assumes that he's willing to answer questions. can he always samp simply say it answering questions and there is no way either under enemy combatant rules or in the criminal justice system to force someone to answer questions who doesn't want to answer them. >> the argument i guess is under this limited questioning period before he is formally advised of his miranda rights,
